Kinda wondering the same thing... but the vf39 outlet isn't really much longer/different vs the td04... about the same physically... either way, it didn't give me much trouble and I'm not going to complain about that-

Hmm wondering about any issues installing JDMSTi TMIC v7 to an 07 US STi. Is my air splitter fine? I was reading this thread and can't find answers for 06-07STi

The real difference in the 2.0 WRX and the 2.5 STI with attaching the intercooler is the throttle body. The 2.5 motors have drive by wire throttle that makes their throttle body longer, shifting the TMIC back/up.

I heard they fit a lot easier on the 2.0 WRX because they were designed to fit with a cable throttle body. The JDM v7 really won't be a big upgrade from your current top mount though.

It might be because I had 2.75" 4 ply silicone connector laying around that I just cut to be the right length after sitting the STi IC where it wanted to be comfortable with the mounts and with the elbow on the turbo outlet..... yesterday I recieved my STi Splitter/seal and that seems to line up fine as well.. (it sits right down inside the IC edges). Only small issue there was that the STi splitter does run into the bottom of the WRX hoodscoop (2002) a little.. I managed to make it fit ok, I had to bend the inside splittler "wing" down a little otherwise the back half of the splittler wasn't going to see much incoming air... getting a Seibon OEM carbon fiber hood pretty soon that comes with an STi style scoop, so then things should work even better.. but it's doing fine for now... after installing the STI IC / splitter etc I did some logging and recorded engine loads and MAF voltages higher than I've ever seen before.. so I'd say it's working

Maybe go for a "later" JDM intercooler? Can't remember when/if they moved over to drive by wire throttles too.

he has a later model STi intercooler (07 STi) , it was pointed above that the jdm v7 intercooler is so ever so slightly larger that's probably not worth the hassle of trying to get it to fit

How long should the aluminum 1 7/8" OD coupler be? I'm installing an STI TMIC from an '05 STI into my '02 WRX w/a vf39. I'm using my Samco y-pipe that had on my old stocker IC.

I just read through the thread but still kind of confused on what I need to get for my 02 WRX.
I have a 02 WRX wagon with the USDM STI TMIC and the 02 JDM hoodscoop.
Currently I'm using an APS splitter and the fit is just slightly off.

If I get RST-9085 from RalliSpec then would I need to buy any additional hardware to make a better seal? RalliSpec's website says the splitter comes with the rubber seal but on post 89(page 4) says I need to get some extra clips?
Another post mentioned that I needed to buy a different rubber seal?
Any clarification would be greatly appreciated.

You can reuse clips, but you will be about 2-4 clips short (don't remember how many). My car has been running without them and so far no problem.

Please note that splitter and shroud won't perfectly aligned with STi TMIC because of longer throttle body hose. I honestly don't think it's that bad IMO.

so basically RST-9085 comes with the rubber seal piece but no clips to attach the seal to the splitter, I just need to either take off and re-use my existing clips or go buy new clips?

You are correct - they do not come with any clips.

Okay, I was able to install this yesterday. PITA to install and having one of the bolts fall in the engine bay did not help. I think it was harder in the beginning but after taking the TMIC on and off I was able to get a technique.

Did any of you have to trim the elbow hose? I think I trimmed it about an inch on each side for the TMIC to install properly. I also reused the original gaskets because I didn't have new OEM ones and I didn't want to use the gaskets that came with the kit.

I tested drove the car after the install and everything felt fine. Boost seemed normal.

can someone tell me how to test for leaks? Noise? No Boost? Everything seems fine but I just want to make sure there's nothing I am missing.

Thanks!

Thanks for the response. I have one more question if you don't mind.
I'm using the APS splitter right now and the seal is not so good, on the back, closest to the firewall, the splitter is about 1 inch too far forward so there is quite a bit of the intercooler that is not covered by the splitter as shown from the picture below, the shiny mark on the left of the intercooler is where the rubber seal comes down when the hood is closed.


Also, the passenger side doesn't seal too well either as shown in this picture.


With the JDM v7 splitter, will I get better coverage and better seal(i.e. the splitter covers all of the cooling surface of the intercooler)

These are extremely expensive($255). I would look for after market or used. Check out the #1 post and get the stylin' motors piece. It needs some trimming but it is WAY less than the stock piece. Oh yeah, the TB piece can be found in the first post as well.
